The larger the sensor the more light the sensor captures yielding in better image quality.

Polaroid Snap: 81.2 x 25.4mm
3. continuous shooting at high resolution
Fast continuous shooting is useful for catching action shots.
Olympus OM-D E-M1 Mark II: 60fps
4. maximum light sensitivity
With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
Nikon D7500 + Nikon AF-S DX Nikkor 18-140mm f/3.5-5.6G ED VR: 1640000 ISO
5. longer battery life
CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
Nikon D3x: 4400shots
6. video recording (main camera)
The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
1080 x 30fps
Fujifilm X-T3: 2160 x 60fps
HTC Re: 65.5g
8. fastest shutter speed
A faster maximum shutter speed allows taking pictures of fast moving subjects without blur.
Sony Cyber-shot DSC-RX100 IV: 1/32000s
9. has a stereo microphone
A stereo microphone allows to record audio files or movies in stereo without an external microphone.

10. has built-in optical image stabilization
Optical image stabilization uses gyroscopic sensors to detect the vibrations of the camera. The lens adjusts the optical path accordingly, ensuring that any type of motion blur is corrected before the sensor captures the image.

11. has AF tracking
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
A microphone port allows connecting external high-end or specialized microphones.

16. has a two-stage shutter
A two-stage shutter is good for taking photos like a pro; apply pressure to the button in order for the lens to focus, and then press it fully to capture the photograph.

17. has continuous autofocus when recording movies
When recording movies they stay focussed and sharp.

Sony Cyber-shot DSC-TX66: 65.29cm³
19. shoots raw
A raw image file contains minimally processed data from the image sensor. Raw files are so named because they are not yet processed and therefore are not ready to be printed or edited with a bitmap graphics editor.

20. has an optical viewfinder
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens sees. There is no time lag and they require no power - as opposed to electronic viewfinders which can drain battery life. They are also better in low light situations.

21. Can create panoramas in-camera
It allows you to take multiple photos capturing different parts of the scene, and then joins them together into a single photo.
